' Application filed Kay 16,

To all whomz't may concern:

Be .it known that I, JOSEPH A. MARINER, a citizen of the United States, and a resident of the borough of Manhattan, in the county and State of New York, have invented certain new and useful Improvements in Hair- Undulating Devices, of which the following is a specification.

My invention relates to hair-undulating devices, and more particularly to a device of this character for producing Marcel waves in the hair, the device being of such character as to be readily handled by one dressing her own hair.

The objects of the invention are to provide a device of the character described which can be readily handled by the person whose hair is to be dressed, thus avoiding attendants, to provide a device on whic the hair may be wound from one end of the device in either direction about its axis so as to facilitate its use by inexperienced persons, and a device by means of which the entire tuft or bunch of hair to be heated at one time will be given a decided set in a few minutes, thus saving time and increasing the permanency of the wave.

The invention consists in the novel features, arrangement and construction of the parts hereinafter described in connection with the preferred embodiment of the invention, and the invention will be more particularly pointed out in the appended claims.

Further objects and advantages of the invention will more fully appear from the following description taken in connection with the accompanying drawings which, by way of example, illustrate two embodiments of the invention.

Referring to the drawings, Fig. 1 is a side elevation of a device embodying the preferred form of the invention;

Figs. 2 and 3 are sectional views taken on lines 2-2'and 3-3 of Fig. 1;

Fig. 4 is a side elevation of a modification arid Fig. 5 is a sectional view of the same taken on line 55.

Referring to the drawings, 1 is a heat-. able metal rod formed of any desired metal from which it may be preferable to make the device, but preferably of some metal such as aluminum or some of its alloys, which may be readily molded in a twopiece mold, and is light and yet of high HAIB-UNDULATWG DEVICE.

heat conductivity. The rod is preferably tapered from one end to the other and is intended to be provided with a handle at the smaller end 2. The rod may be heated in any desirable and well known manner such for example as by an electric heating coil into which the handle end may fit, or which may be located in the rod if it is partly hollowed out.

In 'the form of the invention shown in the drawings the rod is substantially fiattened and is shown in section somewhat in the form of an ellipse so as to provide flattened surfaces 3, 3 and at its ends substantial ridges 4, 4' running longitudinally of the rod about which the hair is bent as it is wound around the rod. These longitudinal ridges or edges may be' referred to as hair-undulating edges since the heating of the hair as itis wrapped over 'and around these edges causes a set or wave in the hair where it wraps over these edges.

In order to provide the rod with suitable guides for guiding the hair as it is wound about the rod, and also to enable the wound hair to be heated on three sides when wound upon the rod, I provide suitable projections 5 for this purpose.

It has been proposed to provide hair curling irons having projections, but these projections have either been in the form of a continuous sinusoidal projection or screw which permits the halr to be wound only in one direction around the iron from one end, or else the iron and projections have been of such form that the hair is intended to be wound back and forth across the longitudinal member and around the alternate projections using them as pegs or fingers, so to speak, aroundwhich the hair is wound. In the present invention the hair is intended to be wound around the tapering rod and the projections are so formed and positioned as to be used as guides for the hair, and also to serve as heating elements for heating the side of the hair wound about the rod, so that substantial heating surfaces are presented on the sides as well as on the bottom of the hair wound about the rod. By making individual projections as distinguished from a continuous sinusoidal or screw projection, it is possible to wind the hair in either direction about the rod from one end thereof, and at the same time to obtainthe desirable side heating surfaces. To accomplish these purposes the projections on one side of the rod are spaced apart and staggered with respect to those on the other side of the rod, and each projection is flattened so that they are wider than they are thick with the direction of their width extending transversely to the axis of the rod. Each projection also preferably has a ridge 6, 6 extending from the sides thereof and facing parallel to the axis of the rod and extending from the base of theprojection up to the top thereof. From these ridges 6 the surfaces of the projections taper to the end edges 7, so that each projection has a flattened side consisting of two tapering surfaces 8 and 9. The projections are progressively spaced closer and closer together from the small end of the rod out to the large end because the tuft of hair will be thickest at the small end, gradually reducing as it is wound out to the large end.

The greatest heating area is provided if the projections extend up from the flattened faces 3, 3, but if for certain uses of the rod it may be desired to have the projections extend from the opposite edges of the rod instead of from the opposite flattened surfaces. then the device may be constructed as shown in Fig. "4 in which the rod 1' is,of the same shape as that shown in Fig. 1, and the projections 55 are of the same general character except that they project from the opposite edges of the tapered flattened rod instead of from the flattened side faces, and are therefore not quite as wide from edge to edge as are the projections on the first form, but their flattened surfaces are of the same general shape in that they have the vertical edges facing parallel with the axis of the rod, and have their sides tapering from these edges toward the ends of the projections.

The construction above described not only has the utility advantages set forth, but it is of very pleasing apperance as a so-called toilet or hair dressing article, and its construction well adapts it to being molded in a two-part mold so that it may be readily drawn from the mold, due to the fact that all of its parts taper from an axial plane respectively toward the top and bottom of the device, as to all surfaces.

In the use of-the device, after it has been heated either by a suitably located electric coil or otherwise, as is well understood, the handle (not shown) is then taken hold of and the end nearest the handle is held close to the scalp and the hair wound, either clockwise or anti-clockwise, as may be desired, around therod in between the staggered projections which guide the hair in a sinusoidal path and at the same time serve, with the surface of the rod, as heat-in 4 means for heating the hair, so that in a ew moments the hair receiv'es the desired set, the

sharp ed es or ridges presented facilitating this set." The taper of the rod is to insure greater uniformity in the length of the Since the tuft of hair is thickest at the roots, if the part of the rod receiving this portion of the hair is of smaller diam eter and the rod gradually tapers to the other end, it'will result in more uniform waves. I

While I have described my invention according to the present preferred embodlments thereof, it will be obvious to those skilled in the art, after understanding my invention, that various changes in the arrangement, form and construct-ion of the parts may be made without departing from the spirit 01' scope of the invention, and I aim in the appended claims to cover all such modifications as come within the scope and spirit of my invention.

Having thus described my invention, what I claim as new and desire'to secure by Letters Patent. is:
